Detailed Description

Represents a floating point number.

Member Function Documentation

Increment()

double Increment ( ) const

inline

Gets the increment of this value.

Returns

Step width.

Exceptions

Any	exception derived from std::exception including CvbException.

The node can take values that are multiples of this one. Except when "nan" is returned which indicates that no increment is available.

Max()

double Max ( ) const

inline

Gets the maximal allowed number for this value.

Returns

Maximal value.

Exceptions

Any	exception derived from std::exception including CvbException.

Min()

double Min ( ) const

inline

Gets the minimal allowed number for this value.

Returns

Minimal value.

Exceptions

Any	exception derived from std::exception including CvbException.

Representation()

NumberRepresentation Representation ( ) const

inline

Gets how the value is to be represented.

Returns

Number representation.

Exceptions

Any	exception derived from std::exception including CvbException.

SetValue()

void SetValue ( double  value )

inline

Sets the value of this floating point node.

Parameters

[in]

value

The new value.

Exceptions

Any	exception derived from std::exception including CvbException.

Unit()

String Unit ( ) const

inline

Gets the unit of this node's value.

Returns

Unit of this node as text.

Exceptions

Any	exception derived from std::exception including CvbException.

Value()

double Value ( ) const

inline

Gets the value of this floating point node.

Returns

The current value.

Exceptions

Any	exception derived from std::exception including CvbException.
